TL;DR: In this paper, the response of elementary flax fibres to tensile tests, as well as to nano-indentation tests on their secondary cell walls, is investigated, at different length scales, via linear viscoelastic rheological models and identification procedures.

TL;DR: In this paper, the mechanical response of amorphous silica under hydrostatic compression for very high pressures up to 25 GPa is modelled via an elastic-plastic constitutive equation (continuum mechanics framework).

TL;DR: In this article, a method to design strongly coupled piezoelectric cantilevers thanks to an analytical approach based on the Rayleigh-Ritz method and a two degrees-of-freedom model, which considers the proof mass inertia effects is presented.

TL;DR: In this article, a new post mortem method is introduced and further compared to three existing classical direct methods by means of a numerical and experimental benchmark covering a large range of materials.

TL;DR: In this article, a quantitative identification of fully densified silica mechanical constitutive behavior is made by using instrumented indentation testing and finite element analyses, based on the use of such an indirect method to assess the mechanical behaviour of this material comes from its brittle behaviour in unconstrained deformation modes usually employed in metals plasticity.
